Hello Guys, How are you all? Hope You all Are Fine. Today I get the following error Paramiko: “not a valid RSA private key file” in python. So Here I am Explain to you all the possible solutions here.

Without wasting your time, Let’s start This Article to Solve This Error.

How Paramiko: “not a valid RSA private key file” Error Occurs?

Today I get the following error Paramiko: “not a valid RSA private key file” in python.

How To Solve Paramiko: “not a valid RSA private key file” Error ?

  1. How To Solve Paramiko: “not a valid RSA private key file” Error ?

    To Solve Paramiko: “not a valid RSA private key file” Error I faced a similar situation and ssh-keygen comes to my help. You should make a copy of id_rsa and convert it to RSA type with ssh-keygen.

Solution 1


I faced a similar situation and ssh-keygen comes to my help. You should make a copy of id_rsa and convert it to RSA type with ssh-keygen.

To Convert “BEGIN OPENSSH PRIVATE KEY” to “BEGIN RSA PRIVATE KEY”

ssh-keygen -p -m PEM -f ~/.ssh/id_rsa

Solution 2

The paramiko.RSAKey.from_private_key_file method requires the private key file to be in “PEM” format. Examine the file you’re trying to read and see if it begins with a line that says:

-----BEGIN RSA PRIVATE KEY-----

If it doesn’t have that line then it’s not PEM.

If it’s not PEM then you’ll have to find some way to create a PEM version of the private key. (EDIT: the original poster used PuTTY’s puttygen utility to export the private key into a PEM-format file.)

Make sure that the new file has the same ownership and limited access permissions that the original id_rsa file has, so that nobody can steal the key by reading the file. Then, obviously, modify your paramiko call to read the key from the new PEM-format file.
